Description

The invention relates to methods for magnetic activation of liquid media. It can be used in the operation of vehicles, in heat engineering and energy, in the production of concrete, reinforced concrete and ceramic products, in the oil, gas and food industries, in medicine, pharmacology, biology, agriculture and other areas of the economy where magnetic activation of liquid , gaseous and viscous mobile media.

Known magnetic resonators "SuperFuelMax", patented by General Motor Corporation on the basis of magnetically rigid ferrites [Patent USA No. 4802931, No. 4496395, No. 7458412, General Motor]. The device consists of five pairs of permanent magnets based on the patented neodymium-iron-boron alloys, combined in two blocks that are rigidly mounted on both sides against each other on the fuel line in the immediate vicinity of the carburetor, injector, or in front of each automobile’s high pressure pump, thus so that the north poles of the magnets of one block are opposite the south poles of the other.

The disadvantage of this device is that the cross section of the fuel line magnetic field will vary significantly. If near the poles it will be equal to 1400-1600 oersted (according to the developers), then in the center of the fuel line (20 mm in diameter) the tension will not exceed 150-300 oersted, i.e. the effect of a magnetic field on different layers of fuel will not be the same. The length of the path along which the fuel is treated with a magnetic field is 50-70 mm. Compensation for changes in the speed of fuel flow during engine operation at different operating modes is not provided. It seems problematic to activate large masses of liquid media using a similar device, since this will require the use of very massive neodymium-iron-boron magnets (the price of which is very high), and they can only be installed on non-ferromagnetic pipes. The design does not provide for the adjustment of the main magnetotropic parameters.

The Pomazkin apparatus is also known [RF Patent No. 2096339, “Pomazkin apparatus for magnetic processing of liquids”, Bull. No. 32, 11/20/97], which contains a solenoidal coil and a housing and a magnetic field concentrator installed inside it in the form of ferromagnetic disks with cutouts located inside the housing at different distances from each other, so that the fluid being processed moves in a zigzag fashion relative to the longitudinal the axis of the apparatus, repeatedly crossing the magnetic lines of force.

The main disadvantage of this apparatus is that in order to create a magnetic field it is necessary to have a solenoid coil, and therefore, an external power source and means of controlling the operating modes of the solenoid coil of the apparatus are necessary.

The technical result of the invention is to simplify the design of the analogue and its operating conditions, i.e. to offer an efficient, autonomous, not requiring external power sources and control of operating modes, easily mounted on the working highways, leading to lower operating costs, ensuring environmental cleanliness of the apparatus.

The problem is solved in that in a magnetic activator of liquid media containing a non-ferromagnetic body, inside which there is a magnetic field lines concentrator, with cutouts forming the working spaces of the apparatus, the magnetic field lines concentrator is made in the form of ferromagnetic plates of at least six pieces, once processed magnetic pulse, creating the most effective working magnetic fields in the treatment area of the activated fluid due to the intrinsic residual induction of the plates, and the working intervals app arata are staggered relative to each other.

Our research [Pomazkin V.A. Nonspecific effects of physical factors on the biotechnosphere objects: Orenburg, Monograph IPK OGU, 2001, p. 340] allow us to conclude that it is not the high magnetic fields, but the fields of 80-120 Oersted that influence the activation of liquid media as efficiently as possible. In addition, the efficiency almost directly depends on the time of exposure to the magnetic field. Therefore, we created magnetic fields in the zone of a moving fluid due to the residual magnetic induction of the ferromagnetic plates of the magnetic concentrator, subjecting them to a single pulsed magnetic treatment. To increase the magnetic rigidity of plates made of ordinary structural steels, we subjected them to thermal hardening. To increase the time of exposure to a magnetic field, the design of our magnetic activator of liquid media, containing a non-ferromagnetic case, inside which there is a concentrator of magnetic lines of force, with cutouts forming the working gaps of the apparatus, provides a zigzag motion of the processed fluid with respect to its longitudinal axis, which allows to extend the path activated substance in a magnetic field several times. To make the fluid move at different speeds during a one-time passage in a magnetic field, the distance between the concentrator plates was made unequal. To increase the effectiveness of the magnetic field, the flow of the treated fluid was divided into very thin layers (up to 0.5 mm).

One of the most important features of our apparatus is the ability to adjust when designing and adjusting all the main magnetotropic parameters: intensity, intensity gradient, residence time, speed of movement in a magnetic field, etc. In this case, it becomes possible to locally adjust the intensity and gradient of the magnetic field strength using the “local demagnetization” method - pulse magnetization. ”

The drawing shows a schematic diagram of a magnetic activator of liquid media.

The activator contains a non-ferromagnetic casing 1, inside of which there is a magnetic field lines concentrator made in the form of ferromagnetic plates 2, of at least six pieces, once processed by a magnetic pulse, creating the most effective working magnetic fields in the zone of processing of the activated fluid due to their own residual induction of the plates , and the working spaces of the apparatus are staggered relative to each other and the adjusting non-ferromagnetic gaskets 3, specifying the distance between the pl astins of the concentrator leading 4 and 5 branch pipes.

The fluid supplied to the apparatus through the inlet pipe 4 passes sequentially with different speeds determined by the adjusting non-ferromagnetic gaskets 3, through the working gaps between the plates of the concentrator 2, which in our apparatus is a magnetic field source after they are magnetized once, is processed in one pass by the optimal magnetic fields tension and through the outlet pipe 5 enters the working line.

The case of a magnetic activator of liquid media, containing a non-ferromagnetic case, inside which there is a concentrator of magnetic field lines, with cutouts forming the working gaps of the apparatus, are made of dielectric, since Foucault currents arising from pulsed magnetic processing of a magnetic concentrator can distort the residual magnetic field topology we create between the working poles of the hub using pulsed magnetic processing. The magnetic field lines concentrator is made of ferromagnetic plates in size equal to the internal cross section of the housing. On one side of each of the plates, working gaps were made so that their area was not less than the internal section of the nozzles supplying the fluid to be treated (so as not to increase the hydrodynamic load of the line). For the manufacture of concentrator plates, you can use ordinary structural steels (which significantly reduces the cost of the apparatus), which, after machining, should be thermally hardened (to increase their magnetic rigidity) or any magnetically rigid ferromagnets. The thickness of the plates and the longitudinal size of the activator is selected from the calculation so that the hub has at least 6-10 plates. To ensure a sufficiently wide range of magnetotropic parameters, it is necessary to take plates of different thicknesses, and to vary the speed of movement of the processed fluid relative to the magnetic field, the working gaps between the plates of the concentrator should be made of different sizes.

The laboratory model of the magnetic activator of liquid media (hereinafter referred to as the apparatus) was made by the authors and tested in the laboratory of the MSTP "Gradient" together with the staff of the departments of general physics, the transport department and the TESMI department of Orenburg State University. The housing of the device 1 is a sealed box of methyl methocrylate measuring 70 × 40 × 40 mm, the top cover of which was removable and sealed through a cardboard strip. At the ends of the body there were inlet 4 and outlet 5 nozzles from a brass tube with an external diameter of 8 mm. The concentrator plates 30 × 30 (2) are made of a steel strip 3, 5 and 8 mm thick. On one side of each plate 2, the working spaces of the apparatus 2 × 26 mm were cut. The concentrator was assembled in such a way that in adjacent plates the cut-out working spaces were on diametrically opposite sides, in a checkerboard pattern. So we tried to ensure that the fluid moved inside the apparatus in a zigzag fashion relative to its longitudinal axis, and the distance over which the magnetic field acted on the activated fluid was lengthened depending on the number of concentrator plates from 150 to 300 mm. The number of plates varied from 6 to 12. The distance between the plates 2 (0.5, 1.0, 1.5, and 2.0 mm) was established using methyl methocrylate or copper foil gaskets. After the assembly of the apparatus, pulsed magnetic treatment of the concentrator was carried out according to the method described in the Pomazkin monograph, forming a magnetic field along its longitudinal axis. For this, the apparatus was placed in a magnetic inductor, which is a coil of five turns of copper wire LPRGS cross-section 2.5 mm, so that its longitudinal axis coincides with the magnetic field vector generated by the inductor, and using the thyristor TL-150 discharged onto it a capacitor bank with an electric capacity of 3,500 microfarads, designed for a voltage of 400 volts. The voltage supplied to the battery was regulated by the LATR-2 autotransformer, converting it into a constant, half-wave rectifier on the D-214 diode. Since the peak pulse current value in the inductor is large enough (up to 5000 A), the concentrator plates are magnetized almost to saturation. After magnetic treatment, we studied the picture of the magnetic field strength, determined by the residual induction of the plates, using one of the varieties of the Akulov-Bitner technique, and determined its value at characteristic points with a F-4355 milliteslameter. The pulse duration is 100 milliseconds. The magnetic field strength, depending on the gap between the plates, ranged from 80 to 150 oersteds. To measure the degree of activation, we used the upgraded standard device TLFP695 / 67M. The strength of experimental concrete cubes mixed with water prepared on our magnetic activator of liquid media increased by 12-15%, and that of ceramic tiles up to 28% compared with similar products mixed with ordinary water. The device turned out to be optimal, the magnetic concentrator of which consisted of 6 plates.

From the foregoing, it is seen that the inventive magnetic activator of liquid media containing a non-ferromagnetic body, inside which there is a concentrator of magnetic lines of force, with cutouts forming the working spaces of the apparatus, in comparison with the analogue and prototype has the following advantages.

1. The product design is greatly simplified and cheapened, because there is no need for a solenoid coil and unique magnetically rigid ferromagnets.

2. Provides full autonomy of the magnetic activator of liquid media, and therefore, complete independence from external power sources of energy.

3. Allows you to obtain magnetic fields that are most effective for the magnetic activation of liquid media.

4. The activating magnetic field for the entire mass of the processed fluid is almost the same.

5. Allows you to increase the exposure time and the distance at which the magnetic field interacts with the activated fluid, 10-15 times.

6. Unlike SuperFuelMax, large volumes of liquid can be activated.

7. In the process of operation requires minimal routine care.
